Today in History, June 6: 1944 – D-Day. Operation Overlord. Future US President, Gen. Dwight D. Eisenhower, had made the solitary decision that the Allied invasion of France would take place on the morning of June 6th, despite bad weather reports. Otherwise it would be a month before conditions were right for the invasion; a luxury he could not countenance with thousands upon thousands of Allied troops getting sick on their transports and every day decreasing the chances that the Nazis would not discover the ruse that was promulgated by a fake army built around Gen. George Patton. Thousands of Allied ships crossed the English Channel and began either bombarding the French coast or off-loading troops. American troops at Omaha Beach rushed ashore amidst withering fire….and saved the world.
